BOTTLE-STOPPER.

SPECIFICATION forming part or Letters Patent in. 650,2 dated ay 1966- Application filed March 14,

To all whom it may concern.-

Be it known that I, THOMAS HOWARD, a citizen of the United States, residing at Ashland, in the county of Boyd, State of Kentucky, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to bottle-stoppers of the type wherein the sealing is efiected by means of a flexible disk jammed against the inner wall of the bottle-neck, and has for its object to provide certain improvements over the construction disclosed in Letters Patent No. 613,066, granted to me October 25, 1898. In said Letters Patent there is disclosed a stopper of the character above described having an air-chamber formed in the body thereof for the purpose therein described; but it has been found that the joint uniting the two sections of said stopper does not prevent access of liquid to the air-chamber therein,and it is this defect that my present invention is designed, primarily, to obviate, which I accomplish by forming the opening into the airchamber at the point where the flexible sealing-disk is located, the latter thus performing the double function of sealing the neck of the bottle and sealing the air-chamber in the stopper against access of liquid.

Certain other minor improvements are also embraced in my present construction, all of which will be definitely pointed out in the description and disclosed in the accompanying drawings, in which- Figure 1 is a sectional view of a part of a bottle, showing my improved stopper applied thereto in the stoppered position. Fig. 2 is a similar view showing said stopper reversed and in the act of being removed from the bottleneck. Fig. 3 isalongitudinal sectional view of my improved stopper. Fig. 4 is a view, partly in side elevation and partly in longitudinal section, showing a slight modification; and Fig. 5 is a detail elevation of still another modification.

Similar numerals of reference denote corresponding parts in the several views.

As shown more particularly in Fig. 3, my improved stopper is formed of a hollow main 1900. Serial No. 83623. (No inodel.)

or body portion 1, containing an air-chamber 2, the lower open end of which is preferably ing-disk 7, it being observed that the diameter of said cap 6 is somewhat larger than is the diameter of the swaged portion 3 of said body portion 1, as is usual in stoppers of this construction in order that the stopper may be inserted into the bottle-neck 8 with the cap 6 downward, but cannot be withdrawn therefrom until the stopper is reversed and the cap 6 is upward.

As shown, the cap 6 is provided with an enlargement 9,into which the screw 5 projects,

though the same is not essential, as the screw 5 may be formed integral with the cap 6, it being necessary only that said screw shall not project through the cap in order that the liquid may not follow the thread of said screw and thus enter the air-chamber 2. For convenience in removing the stopper from the bottle I preferably form on said cap 6 a bridge 10, with which to engage a suitable hook 11 for withdrawing said stopper reversed from the bottle, as shown in Fig. 2, though, if desired, I may dispense with said bridge and extend the enlargement 9, as shown in Fig. 5, into a knot 12, adapted to be engaged by a suitable bifurcated hook, as will be readily understood.

It is sometimes desired to provide a means for engaging the upper end of the stopper in order to temporarily uncork a bottle, and this I accomplish by providing a cap 13 on the upper end of said stopper, the same being attached thereto by means of a screw 14 and being provided with a bridge 15, as shown in Fig. 4, though said bridge may be dispensed with and a knob, such as shown at 12, employed.

The material of which the stopper is composed may be some light metal, such as aluminium, or some such material as hard or vulcanized rubber, the air-chamber 2 atretained between said body portion and" cap fording the necessary buoyancy and providing that the" stopper will automatically" as,-

sume the position shown in Figs. 1, 3, and 4;

whereby it automatically corks the bottle when filled with aerated liquid.

Having thus described my invention, what I;claim, and desire to secure by Letters,l?at en t,is- 7-" 1. Abottle-stopp'er formed in'two parts detachably connected together and-provided with an air-chamber therein, having a sealing-disk retained between said parts, said against ingress-of liquid, substantially asset, forth.
